Õ
letter of the Latin alphabet; used particularly in Portuguese, Estonian, and Vietnamese
Õ (uppercase), or õ (lowercase) is a composition of the Latin letter O with the diacritic mark tilde.
Romagnol
For Romagnol language, õ is used in some proposed orthographies to represent [õː], e.g. savõ [saˈvõː] "soap". To this day a unified standardization has not been established.
Silesian
In the Silesian language, õ represents a dialectal letter representing [o], [a], [aum], [oum], and appears as the 22nd letter of the Ślabikŏrzōwy Szrajbōnek, one of the major Silesian alphabets.
Estonian
In Estonian, Õ is the 27th letter of the alphabet (between W and Ä), and it represents a vowel characteristic of Estonian, the unrounded back vowel /ɤ/, which may be close-mid back, close back, or close-mid central. The vowel was previously written with the letter Ö, but in the early 19th century, Otto Wilhelm Masing adopted the letter Õ, ending the confusion between several homographs and clearly showing how to pronounce a word.
In informal writing, e.g., emails, instant messaging and when using foreign keyboard layouts where the letter Õ is not available, some Estonians use the characters O or 6 to approximate this letter.
In most parts of the island Saaremaa, Õ is pronounced the same as Ö.
Guaraní
In Guaraní, Õ is the 22nd letter and fourth nasal vowel of the alphabet, similar to the Portuguese "õ", but with somewhat less stressed nasalization.
Hungarian
In Hungarian, Õ only appears when a typeface (font set) does not contain a proper "ő" letter, which is an "o" with a double acute diacritic.
Begin with the source’s own compact description: “Õ” is letter of the Latin alphabet; used particularly in Portuguese, Estonian, and Vietnamese. The dossier treats that line as a proposition to test through letter, Latin and alphabet, not as a finished interpretation.
Why this record matters
The phrase “letter of the Latin alphabet; used particularly in Portuguese, Estonian, and Vietnamese” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Named sources, stable identifiers and responsible institutions provide the strongest route from overview to verifiable evidence. The source revision retrieved here is dated Aug 21, 2026. The linked authority identifier is Q278142. None of the 0 selected statements returned an explicit reference.
Overview language is designed for orientation and should not be treated as a substitute for the evidence cited beneath it. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
